DEFINITION

Classification: 318/454

(under subclass 453) Subject matter in which the sensing means respond to two or more predetermined electrical conditions, one or more of which conditions are different in kind or character (e.g., voltage, current, frequency, watts, power-factor, etc.) than one or more others of the conditions.

(1) Note. The magnitude of an electrical characteristic (e.g., 50-volts, 10 amperes, etc.) and the rate-of-change of magnitude of the same characteristic (e.g., 1-volt per second change, or 2-amperes per minute change) are considered to be diverse electrical conditions and, hence, are included within the definition of this subclass.
